With the next commit, if I run
docker/docker_run_tests.sh --shell-after docker/jammy-asan-clang.Dockerfile
I get this in test_string.fish and test_git.fish:
=================================================================
==8339==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 72 byte(s) in 1 object(s) allocated from:

SUMMARY: AddressSanitizer: 72 byte(s) leaked in 1 allocation(s).
Strangely there is no tparm in the call stack. It does not seem to happen
in CI.
This makes "ninja test" write only to the build directory, not to the source
tree. This enables our docker script which mounts the source as read-only.
Some tests create files like "./test/test-home". Traditionally the did so
in the first parent directory that contained tests/test.fish; so either a
build directory or the root.
The new rust version always changes directory to the root. This blows up
when running with our docker/ files, which mount the source as read-only.
Fix this by always changing directory to the build directory.
In future we could extend this to not chdir if FISH_BUILD_DIR was not
specified, to match traditional behavior. No strong opinions here.
Update the pydoctheme.css file to add support for print media.
The code was adapted from the existing support for screens that are less than
700px wide, with the following changes:
- Remove the documents and sections index
- Remove the quick search
- Remove dead CSS code
Additionally, add section numbers and ensure that code blocks are never split
across multiple pages.
GNUInstallDirs is what defines CMAKE_INSTALL_FULL_BINDIR and such, so
the setting in Rust.cmake didn't work.
This also makes build.rs error out if any of these aren't defined
This would highlight `$var["foo"]` as an error because
parse_util_slice_length didn't advance the iterator.
There's got to be a nicer way to write this.
The C++ code implicitly relied on wrapping behavior.
There are probably more cases like this. Maybe we should disable
"overflow-checks" in release mode.
This would crash from the highlighter for something like
`PATH={$PATH[echo " "`
The underlying cause is that we use "char_at" which panics on
overread.
So instead this implements try_char_at and then just returns None.
This is more correct - we don't want to change how we encode this
string in the middle of encoding it, and also happens to be a bit
faster in my benchmarks because this is actually a function call
according to valgrind.
We assume that you use something like hyperfine to run warmups, like
our driver script does.
This allows the script to be run e.g. in valgrind without being too
much of a pain in the gluteus.
Iterator::last() consumes the entire iterator, even for DoubleEndedIterator,
see https://github.com/rust-lang/rust/pull/28125#issuecomment-145070161
Because of this, "at_line_start()" took 90% of
fish_indent share/completions/git.fish
making it take 1000ms instead of 30 ms. Fix that.
